extract subcircuit parameters from OCEAN?

[JD]

Hi,

I am trying to extract some subcircuit parameters using OCEAN scripts.

The subcircuit looks like

subckt nmos (d g s b)
parameters
+ a = 20
+ b = 20
+ w = 1
+ l = 0.25
.....

model nmos bsim3v3 type=n
.....
.....
.....

nmos_a (d g s b) nmos l=l w=w ....

ends

Now I want extract parameters a, b for each nmos subcircuit from OCEAN.


I tried:

designParamVals info what=parameters where=rawfile

when I open this result in OCEAN, only "top-level" parameters are
shown.

Any suggestions?

Thanks

JD

That would be done using:

allp info what=allparameters where=rawfile

However, this currently results in:

allp: writing subcircuit instance parameters to a rawfile is not
currently supported.

There is a PCR for this:

PCR: 786809
Title: Support where=rawfile in the subcircuit parameters probing

(the title is not exactly obviously named...)

So the best thing if you want this is to contact customer support, and then you
can be added to the customers asking for this - which increases the likelihood
of it being implemented sooner rather than later.

Best Regards,

Andrew.
